HEADLIGHT.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed March 11, 1908. Serial No. 420,481.

The object of the invention is to provide locomotive head an improved form of pivotally mounted f light arranged to throw the rays of light in the direction in which the engine moves. as when passing around a curve.

A further object of the invention is to simplify the means whereby this may be done. The invention consists in certain novel features of construction and arran ement of parts. hereinafter fully described. illustrated in the accompanying drawings. and specifically claimed.

in the accompanying drawings :Figure 1 is a front elevation of a locomotive constructed in accordance with the invention, parts being broken away to show the same. Fig. 2 is a side elevation of a portion of a locomotive arranged in the same manner. Fig. 3 shows one manner of supporting the head light. Fig. 4 shows a detail of one of the. parts thereof. Fig. 5 shows another manner of supporting the head light.- Fig. 6 is a detail of one of the lever connections.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The numeral 10 indieates'the locomotive smoke box on which is held a bracket 1 1 having mounted thereon a rotatable platform 12 and a head light 13 is detachably held on said platform. In the form shown in Fig. 3 it will be noted that cross bars 1-1 support a pin 15, and the platform 1?. is carried on a sleeve 16. It is preferred. however, to use the previously described form, as shown in Fig. 5, and there equip the same with rollers 17 to decrease the friction of rotation.

A pin 18 projects from the front of the head light or its support, preferably in substantially horizontal direction. Mounted upon the engine truck is a pin 19 securely fixed thereon. On the pin 19 is a sleeve 20 rotatable and slidable thereon. It is preferred to form this sleeve with a forked end, asshown at 21.. A lever 22 is intermediately fulcrumed as shown at 23, and it is to be noted that, if desired, one of the smoke box front bolts may be used. for this fulcrum. The lever 22 is provided with a suitable opening therethrough. and the forked end 21 of the sleeve ZO'is. also, provided with openings adapted to register with the opening in the lever and a bolt 24: is arranged to pass through these openings and pivotally connect the lever and sleeve. A record lever 25 pivoted as at 26 is held to be slidably pivoted to the first lever. as at 27. The fulcrum at 26 may consist of a bolt which supports the number plate, as here shown. or such other device as may be adopted. On the upper end. of the lever 25 is formed a pin 2% whereon is mounted a sleeve 29 which is here shown provided with a forked end 30. although any readily observed that when the truck swings to one side -or the other, as indicated at the dotted lines in Fig. 1, the lower end of the lever 22 will be swung to the same side. At the same time due to that end moving in the are of a circle, the end will rise slightly being permitted to do so by the slidable connection between the pin 19 and the sleeve. 20. The pin 19 will. also, be caused to rotate slightly in the sleeve 20, inasmuch as the lever will prevent the sleeve 20 from moving except in a fixed plane, while the pin 19 moves in the arc of a circle of comparatively great radius. The upper end of the lever 22 will be caused to move in the opposite direction and carry the lower end of the lever 25 with it, the slot and pivot connection between the two levers permitting this movement. The upper end of the lever 25 will thus be caused t1) move in the same direction as that in which the truck swings and the slotted sleeve 2) permits freedom in this movement ina manner similar to that of the sleeve .20 before described.

It is a well known fact that there is more or less vertical movement of the. trucks of a locomotive relative. to the boiler and parts carried above the frame, and it is, therefore, necessary that some freedom of motion be provided and this has been done in the various slidable and rotatable connections shown in the present invention.

The various parts heretofore described are. so connected that there is a slight degree ofency or spring.

lay in the slidin 'oints thereof further, the P material of whio the device is made is intended to have a certain amount of resili- By this means allowance is made for the slight forward and backward motion caused by the pin passing through the arc ofacircle.

It is obvious that while the device is here shown as a lied to a locomotive, and while it is especia y well adapted for this purpose, yet the same may be used on road engines or other motors analogous thereto. It is' not desired therefore to confine the application of the device simply to locornotives but to'include all such as 'roperly come scope of the invention.

It will be further-obvious that this device may be used u on thesideof the engine, as

well as on the ront thereof. To'accomplish'. this result it is merely necessary to move the .pin 19 to a suitable position onthe, truck andrearrange the pivotal supports for the lever.

' What is claimed is 1. In a'device of the character described, a pivotally mounted truck, a pivotally mounted headlight, a. lever, a pin rigidly fixed on said truck, a sleeve held to freely rotate and slide on saidpin, means for connecting said sleeve and said lever, and means for connectingsaid lever to the headlight'toswing the same as the truck swings.

within the 4 lever comprisin' a pin fixed on said truck and a sleeve'pivota ly att'ached tosaid lever, a second lever slidably; pivoted to the first lever, a'pin formed on said second lever, a sleeve having a slot, rotatably mounted thereon, and a in projecting from-the headlight into saidot.

' 3. In a device of the character described, a

,' pivotally mounted truck, a 1pivotally mounted roller supported headlig truck, a sleeve held to rotate andslide on t, a pin on said said pin, an intermediatelyfulcrumed lever ivotally connected to said sleeve, a second lntermediately fulcrumed lever, a sliding pivot connection betweensaid levers, a in ormed on said second lever, a sleeve having a slot,'rotatably mounted on said pin, and a pin on said headli ht held in said slot.

In testimony t at we claim'the foregoing ,as our'own, we have hereto affixed our signatures-in the presence oftwo witnesses.
